习惯性的中到高强度体力活动可以减轻动脉硬化。然而，目前尚不清楚轻体力活动是否也减弱动脉硬化。目前还不清楚轻度体力活动是否对健康和不健康的人有同样的影响。进行这项横断面研究，以确定用三轴加速度计测定的轻体力活动量与动脉硬度之间的关系。共有538名健康男性和女性参与了这项研究。每个年龄组的受试者根据每天在轻度体力活动中花费的时间分为高光或低光体力活动组。动脉硬度通过颈-股动脉脉搏波速度测量。双因素方差分析显示年龄和轻体力活动时间在确定颈-股动脉脉搏波速度方面存在显著的交互作用（P
Habitual moderate-to-vigorous-intensity physical activity attenuates arterial stiffening. However, it is unclear whether light physical activity also attenuates arterial stiffening. It is also unclear whether light physical activity has the same effects in fit and unfit individuals. This cross-sectional study was performed to determine the relationships between amount of light physical activity determined with a triaxial accelerometer and arterial stiffness. A total of 538 healthy men and women participated in this study. Subjects in each age category were divided into either high-light or low-light physical activity groups based on daily time spent in light physical activity. Arterial stiffness was measured by carotid-femoral pulse wave velocity. Two-way ANOVA indicated a significant interaction between age and time spent in light physical activity in determining carotid-femoral pulse wave velocity (P
